  • Heat is also exchanged in the second container by condensing vapor, collecting liquid and maintaining the liquid fluid in the second container at a certain level.
  • the heat exchangers are not completely absorbed within the liquid fluid. With portions of the heat exchangers overlying the liquid fluid, fluid vapor generated in the first container is kept warm in the vapor storage space to prevent the vapor from condensing again. This shows that the level control in the first container is advantageous because it can be achieved so that the evaporation can be effective, since the heat exchanger is constantly surrounded at least in its partial area by liquid.
  • the heat exchanger in the second vessel is fed with a lower temperature heat transfer medium to liquefy (condense) the vaporous fluid after it has exited the engine.
